Cleaning composition



Patented Nov. 19, 1929 UNITED STATES PATENT OFFICE SAMUEL '1. SHEBRIOK, OF DENVER, COLORADO, ASSIGNOR TO EDWIN S. KASSLEB, J'B., AND THOMAS P. OAIEBELL, OF DENVER, COLORADO, TRUSTEES CLEANER G COMPOSITION No Drawing.

This invention relates to a composition of matter particularly adapted for use in cleaning walls and other surfaces.

The main object of the invention is to rovide a composition of the above-stated 0 aracter having superior absorbent and plastic properties and a stability both physical and chemical which adapts it particularly for the purposes for which it is intended.

A composition made in accordance with my invention is furthermore distinguished by its great resistance to deteriorative influences.

A further object of the invention resides in the provision of a composition of matter for use as a cleaner, which is very simple and inexpensive both in preparation and in use.

With the above and other objects in View, the composition has for its principal ingredient a colloidal or jelly-forming clay such as bentonite (Al O .6SiO .5H O) or other hydrated silicate of aluminum.

The composition forming the subject of the invention involves the use of a plastic mineral substance containing as components, a gelatinous colloid, a mineral salt and an insoluble clay in a state of fine subdivision, and bentonite or other clay of similar nature lends itself articularly to the production of the desired substance especially when subjected to an acid treatment for the production of ortho-silicic acid. The natural clays contain a considerable amount of combined silicic acid and by treating the material with a comparatively stronger acid, part or all of the silicic acid may be displaced and recipitated, in acidic environment, as ge atinous ortho-silicic acid (Si(OH Sulfuric acid is well a apted for the acid treatment of the clays although other acids, particularly those which form a soluble salt of aluminum, such as hydrochloric or glacial acetic, ma be used in difierent proportions with satis actory results.

The cla s after the acid treatment yield a compoun of colloidal clay, aluminum sulfate, ortho-silicic acid and water that meets all the requirements for the production of a cleaning compound of the above-described properties and also for the production of Application fled October 25, 1927 Serial No. 228,690.

other materials such as an adhesive, lubricant compounds or polishing compounds as will be described in other applications for atent.

To make a cleaning compound by t e use of a colloidal clay such as bentonite, acid treated, flour and a salt (NaCl) are added in addition to the acid, and the following proportions have been found to give highly satisfactory results: bentonite 2 parts; su furic acid (concentrated C. l part; flour, 1 part; salt (NaCl), 2 parts.

The same or similar proportions ma be adhered to in mixing the cplloidal clay, our, and salt without the acid.

The mixture is made up cold, then heated to boilin in the presence of a large excess of water. on coolin the excess water may be drained off or ecanted after settling, leaving a product ready for use as a cleaner.

Having thus described 111 invention, what I claim and desire to secure y Letters Patent 151- 1. Themethod of producing a composition of matter, consisting in treating a colloidal clay with acid to displace silicic acid in the clay as ortho-silicic acid, intermixing the clay with flour and salt, bringing the mixture to its boiling point in the presence of water, and separating excess water after settling.

2. A composition of matter comprising acid-treated bentonite, flour and salt.

3. A composition of matter comprising acid-treated bentonite, flour, salt and water.

4. A composition of matter comprising acid-treated bentonite two and one-half parts, flour one part, and salt two arts.

In testimony whereof I have a signature.

SAMUEL T. SHERRICK.
